What is a CVV code?
For your safety and security, Asda requires that you enter your card verification value (CVV) code when paying via credit card.
The CVV code is a three-digit number which appears on the back of all Visa, Mastercard, Solo and Electron cards.
On American Express cards, it is a three or four-digit number which appears on the front of the card.
Credit card orders that do not include CVV codes will not be processed.
